Description andreas bittner 2013-09-24 16:38:34 UTC

User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:23.0) Gecko/20100101 Firefox/23.0

I remember quite vividly that I used to report similar bugs and these ipv6 madness many opensuse versions back 12.1 and others come to my mind e.g. <https://bugzilla.novell.com/show_bug.cgi?id=765638>

so today trying a zypper dup from a 13.1/m4 to 13.1/b1 on an ipv4-only host (and ipv4-only network, with ipv4-only ISP) eventually fails sometimes during fetching one or another package.

var/log/zypper.log shows the ipv6 curl errors that it cannot reach the ipv6 address.

this is a real shame. is it possible to sort these ipv6 mad bugs out ever? or is there just no solution to this?

ever since ipv6 came along to get more wider adoption with opensuse it has been a huge pain in many areas of the distro :(, when actually trying to NOT use it, or trying to stay away from it or being unable to use it due to ISP limitations and so on.

Comment 1 Jiri Bohac 2013-09-27 18:26:41 UTC

I tried to reproduce this but failed. Is there an easier way to reproduce this, e.g. using curl directly with an URL that always fails?

Please also provide the output of:
ip a l
ip -6 r l
ip r l
sysctl -a

Thanks!

Same as bnc#780179.
